FAN ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 373,366, dated November15, 1887.

Application filed September-2, 1886. Serial No. 212,526.

To aZZ whom it may concern: Be it known that I, H. HERBERT HERRING- TON,a citizen of the United States of America, residing at Macon, in thecounty of Bibb and State ofGeorgia,have invented certain new and usefulImprovements in Fan Attachments for Sewing-Machines; and I do herebydeclare the following to be afull, clear, and exact descrip tion of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

My invention relates to certain new and useful improvements in fanattachments for sewing-machines, the object of myinvention being toprovide a fan attachment which can be adjusted to and from thedriving-wheel of the sewing-machine, the parts of which are constructedso that the friction-wheel of the fanshaft canbe adjusted verticallythereon andthe fans raised or lowered on said shaft.

My invention also consists in the construction and combination of theparts, as will be hereinafter set forth.

In the accompanying drawings, which illustrate my invention, Figure l isa perspective view of my improved fan attachment, showing the sameapplied to a sewing-machine. Fig. 2 is a detail perspective view of thedisks for securing the stems of the fans to the vertical shaft. Fig. 3is avertical sectional view showing the disks in position upon thevertical shaft. Fig. 4 is a sectional view of the friction-disk. Fig. 5is a perspective View of the plate and screw for securing the vfanattachment to the sewing-machine table, and Fig. 6 is a sectional viewof the lower part of the att-aehment.

In the accompanying drawings, A refers to the balance-wheel of thesewing-machine, said balance-wheel being usually provided in almostevery style of sewing-machines with acentrally-projectingportion,a,which is formed integral with saidbalance-wheel, and it is against the plane face of this projectingportion of the balance-wheel which the friction-v disk should contact.

At a suitable point the sewing-machine table is cut away or recessed, asshown at B, for

(No model.)

the reception of a plate, I), which is provided centrally with akey-hole slot, through which projects a bolt which is provided with arectangular portion adjacent to the, head thereof. The key-hole slot inthe plate I), when the same is secured to the sewing-machine table,should be parallel with the length of said table, so that theshaft-support can be adjusted .to and from the sewing-machine.

0 refers to the shaft-support, which preferably consists of a castingmade in a single piece, said casting being'provided with a flat baseportion, 0, which is provided at its inner'end with anupwardly-projecting bearing, c,which is provided with acentral V-shapedsocket, d, within which the lower end of the vertical shaft D will bear,said shaft having the lower end thereof shaped to correspond therewith.By providing the lower end of the shaft with a V-shaped socket it willautomatically take up the wear. A

The casting 0 between the front edge of the upwardly-projecting standardand the bearing 0 is provided with a perforation, 6, through whichpasses a bolt, over the threaded portion of which is placed a thumb-nut.By tightening this thumb-nut the casting can be readily secured to thesewing-machine table. The standard Ohas at its rear portion a projectingweb for giving stiffness thereto, and its upper portion is bent at rightangles and extends over the bearing 0', where itis provided withavertical perforation, through which passes' the shaft D, so as tomaintain the same in a vertical position. v

E refers to a friction disk or wheel,which is provided centrally with anupwardly-projecting hub, f, which has a transverse perforation which isscrew-threaded for the reception of a screw, f, by means of which thefriction-disk can be adjusted vertically upon the shaft D, and byproviding this friction-disk with the aforesaid means for verticallyadjusting the same its position can be varied, so that the edge of saidfriction-dislc can be made to abut against the centrally-projectingportion of the balance-wheel of the sewing-machine at the de sireddistance from the center thereof, so that the speed of the rotation ofthe fans may be varied at the will of the operator. The periphery of thedisk E is recessed on its under side and provided with a seriesofperforations, through which may be passed rivets or bolts for securingin place a washer, E, of solid leather or other equivalent material. Byproviding the disk with a circumferential recess the leather washer,which projects at a considerable distance therefrom, will be preventedbending upwardly, which is the only direction in which it would have atendency to bend.

Thelower disk,G,which holds the stem ofthe fan in place, is providedwith a hub or central socket, g, the upper portion ofwhich isscrewthreaded for the reception of a clamping-nut, 9, while the lowerprojecting portion has a screw-threaded recess for the reception of aset-screw, h. The upper disk, G, is provided with a series of dependingportions, 1', which are provided centrally with V-shaped recesses,within which will lie the stems or handles of the fans, and said upperdisk is provided centrally with a perforation of sufficientsize to fitover the upwardly-projecting portion of the hub of the lower disk.

\Vith my improved attachment, ordinary fanssuch as are known asJapanesemay be employed, or ordinary ornamental advertising-fans, andsaid fans may be secured in the disks so as to be eitherat right angleswith said disks or inclined thereto.

The device hereinbefore dcssribed is simple in construction,and theparts are capable ofadjustment, so that the attachment can be applied toevery sewing-machine, and by adjusting the supporting-frame of therotary shaft to and from the projecting portion ofthe balancewheel thespeed of the fans may be regulated, and the fans can be adjustedvertically on the shaft, so as to be at any desired distance above thesewing-machine.

The device hercinbcfore described is not only adapted to be employed onsewing-machines, but may also be used with any other mechanism desired.

I am aware that prior to my invention it has been proposed to attachrevolving fans to a sewing-machine; also to provide such a revolving'fanwith a standard, over which is placed a tube which carries the fans anda friction-disk, said friction-disk resting upon the upper edge of thebalance-wheel, and I do not claim such invention, as in such a case thefans can only be made to rotate in one direction, whereas with myimproved device, by moving the friction-disk above or below the centerof the shaft of the sewing-machine, the direction of the rotation of theshaft may be varied. This is desirable in some cases, as the fan isemployed not only for fanning the operator of the sewinginachine, butalso for causing a draft of air to be directed upon thework, so as tokeep the same free from lint.

What I claim as new,and desire to secureby Letters Patent, is

In a fan attachment constructed substantially as described, a clamp forthe stems of the fan, consisting of a disk having a hub projecting oneach side of said disk, the lower portion having a screw-threaded recessfor the reception of an adjusting-screw, the upper portion beingscrewthreaded externally for the reception of a clamping-nut, and adisk, G, having downwardly-projecting portions with angular recesses, incombination with the shaft D, supports therefor, and means for rotatingsaid shaft, substantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

H. HERBERT HERRINGTON.
